摘要
风化花岗岩的路用性能较差,通常不能直接作高速公路路基填料,但可以通过改变施工工艺的方法,提高风化花岗岩压实度,可以使其满足规范要求。以通平高速公路为依托工程进行现场碾压试验,通过分析不同的碾压遍数、强振频率、含水量对压实度的影响,对比得出风化花岗岩的最佳碾压工艺。
In most cases,the weathered granite is restricted to the application of highway subgrade filling material because its poor road performance.However,the degree of compaction of the weathered granite can improve through construction technology,and it can meet standard requirements.Field rolling technology test were carried out based on project of Tongping Expressway.In this paper,from the strong vibration frequency,compaction number and moisture content on the degree of compaction were analyzed.The rational construction technology of the weathered granite was obtained through comparison.
